"The water ripping over the Bluff Bridge at the moment is probably going about 40 miles an hour," he said.

"It's raging, it's actually a torrent, it's like about 30 metres back from the centre of the bridge where the water is but the current in the river itself is actually barrelling along there at a great rate of knots.

"There's a whole lot of little creeks, and just keep your kids away from the creek because if they get caught they'll be swept away in no time," he said.

Trevor Wingfield, from The Gorge at the head of the Clarence catchment, says isolation is just part of life on the land.

"We'll be shut in for about fours days... after all this rain because the river's up," he said.

"We have no worries about that, we have four deep freezers and they're always full all the time.

"We get cut off a lot here we do because (the) road follows right along the river banks and that and out towards the end of our road we have a big creek there... it cuts us off for two weeks when it's really raining," Mr Wingfield said.

Parts of the Pacific Highway remain closed this morning due to heavy rain and flash flooding.

The road is closed in both directions between Macksville and Nambucca Heads, on the Hastings River Bridge at Port Macquarie, and at Gould Lane near Clybucca.

The RTA says only one lane of the Pacific Highway is open at Corindi, north of Coffs Harbour.

The Orara Way is closed north of Nana Glan, and the Waterfall Way is closed at Dorrigo Mountain.

Drivers are being urged to take extra care.

Meanwhile, the Clarence Valley Council is still counting the cost of damage caused by a landslide in Yamba.

The council's deputy general manager, Rob Donges, says Yamba Street was divided by a centrepiece that collapsed during this week's heavy rain.

Mr Donges says the top section of the road has now fallen onto the bottom of the street.

"We've closed roads off there and once the weather settles down, if that's ever going to happen, we'll have to get some geo-technicians in there to do some testing to work out how we're going to be able to reconstruct that road so this won't happen again," he said.

"It's the extension of one of our main roads in the village and it heads off to our very popular beaches so yes, it is well used.

"I've got no idea at this stage (about the cost of repairs), but it doesn't look cheap that's for sure.

"If we can return it to an earth embankment as it was previously it mightn't be too bad, but if we're required to put some hard engineering work in there like retaining walls or the like it could be a considerable expense," Mr Donges said.

And the manager of the Red Rock Bowling Club says he doesn't know how long it will take for things to return to normal after yesterday's tornado.

About two thirds of the club's roof was ripped off when savage winds ripped through the village early yesterday morning.

Brian Taylor says the clean-up is continuing this morning.

"Yeah so it's clean-up day today and get the insurance people out and try and get the club back on deck again," he said.
